WALTER F. VALTERS, OF CHICAGO, ILLINOIS.

BOOKBINDING.

Specification of Letters Patent.

Application filed May 10, 1912.

Patented Apr. 15, 1913. Serial No. 696,298.

To all whom it may concern Be it known that I, WALTER F. VALTERS, a subject of the King of England, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Bookbinding, of which the following is a specification.

My invention relates to improvements 1n book binding, and the object is to provide a book composed either of signatures or separate single sheets securely bound together in a simple and efficient manner.

This invention is equally adapted for binding new books and for re-binding old books, and consists in the combinations and arrangements of parts hereinafter described and claimed.

My invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which- I Figure 1 shows an elevation of the bind ing edges of four sections of a book slightl separated and bound in accordance with my invention, Fig. 2 represents a view, in

perspective, of the first section of the book, and Fig. 3 represents a plan view of one sec tion of the book.

The preferred form of construction, as illustrated in the drawings, comprises a plurality of signatures or sections of separate loose leaves 4 arranged in proper order and provided with recesses 6 across the bind ing edges of each section or signature in positions so that the recesses in one signa ture or section will register with the recesses in each of the other of such signatures or sections. In each of the recesses 6 is secured a cord 5 providedfor the purpose of strengthening the binding of the book, or, when so desired, a ribbon or other suitable means may be substituted in place of such cord and the recesses 6 may be dispensed with.

The signatures or sections of leaves are preferably perforated with a series of perforations 8 near their binding edges, as in dicated in Figs. 2 and 3, in positions so that the perforations in one signature or section will register with the perforations in each of the other signatures or sections. When it is desired, the perforations 8 may be dispensed with and the needle or otherinstrument with which the book is sewed used to The thread 9 is guided, in sewing the book, by

means of a suitable needle 10 and firstpassed through a perforation'S at one corner of the first section or signature and tied or otherwise secured, as indicated in Fig. 2, carried along and through the third perforation, laced across its binding edge crossing the first reinforcing cord 5 and through the fifth perforation, then recrossing the first reinforcing cord 5 and through the fourth perforation and again recrossing the first reinforcing cord 5, then across the edge portion again and through the seventh per foration, crossing the second reinforcing cord 5 and through the ninth perforation, then recrossing the second reinforcing cord 5 and through the eighth perforation, then again recrossingthe second reinforcing cord 5 and through the eleventh perforation, then crossing the third reinforcing cord 5 and through the thirteenth perforation, ,then recrossing the third reinforcing cord 5 and through the twelfth perforation, then again recrossing the third reinforcing cord 5 and through the fifteenth perforation, then across the binding edge and through the sixteenth perforation. The second section or signature is sewed by means of then passing the thread 9 across the binding edges of the first and second sections and through the sixteenth perforation in both the second and first sections, then across their binding edges and through their fourteenth perforations, then across their edges crossingthe third binding cord 5 and through their twelfth perforations, then recrossing the third binding cord 5 and through their thirteenth perforations, then again recrossing the third reinforcing cord 5 and through their tenth perforations, then across the second reinforcing cord 5 and through their eighth perforations, then recrossing the second bind ing cord 5 and through their ninth perforations, then again recrossing the second reinforcing cord 5 and through their sixth perforations, then crossing the first reinforcing cord 5 and through their fourth perforations, then recrossing the first reinforcing cord 5 and through their fifth perforations, then again recrossing the first reinforcing cord 5 and through their second perforations, then across their binding edges and through their first perforations to complete the sewing of the first and second sections together. The first, second and third sections are next sewed together by passing the needle over their binding edges and through their first perforations, then across their binding edges and through their third perforations, then across the first reinforcing cord 5 and through their fifth perforations, then recrossing the first reinforcing cord 5 and through their fourth perforations, then again recrossing the first reinforcing cord 5 and through their seventh perforations, then crossing the second reinforcing cord 5 and through their ninth perforations, then recrossing the second reinforcing cord 5 and through their eighth perforations, then again recrossing the second reinforcing cord 5 and through their eleventh perforations, then crossing the third reinforcing cord 5 and through their thirteenth perforations, recrossing the third reinforcing cord 5 and through their twelfth perforations, then again recrossing the third reinforcing cord 5 and through their fifteenth perforations, then across their binding edges and through their sixteenth perforations to complete the sewing of the first set of three signatures or sections together. The fourth section or signature is then secured by sewing the second, third and fourth sections together. This is accomplished by passing the thread 9 across the binding edges of all these sec tions through their sixteenth perforations, then across their binding edges and through their fourteenth perforations, then across the third reinforcing cord 5 and through their twelfth perforations, then recrossing the third reinforcing cord 5 and through their thirteenth perforations, then again recrossing the third reinforcing cord 5 and through their tenth perforations, then crossing the second reinforcing cord 5 and through their eighth perforations, then recrossing the second reinforcing cord 5 and through their ninth perforations, then again recrossing the second reinforcing cord 5 and through their sixth perforations, then crossing the first reinforcing cord 5 and through their fourth perforations, then recrossing the first reinforcing cord 5 and through their fifth perforations, then again recrossing the first reinforcing cord 5 and through their second perforations, then across their binding edges and through their first perforations completing the sewing of the second, third and fourth sections together. In a like manner the third, fourth and fifth sections are sewed together, the thread 9 being resewed through such sections, each time the sewing passes a reinforcing cord 5, as described above, and this method followed until all of the sections or signatures of the book are secured. The last and next to the last sections and the last-section are sewed in a manner similar to sewing the first and second and first sect-ions already described. The reinforcing cords 5 are secured to the sides of the book (not shown), and

such sides are secured to the book proper in the usual fashion.

Vith a book made in accordance with my invention, it may be opened fiatly between any two leaves, as the sewing produces equal strain on each of the leaves in the book. It has the advantage of securing the reinforcing cords 5 with a greater number of threads, thus reinforcing the sewing at these points, making it particularly adaptable for use in binding single leaves or leaves of old books into book form.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the exact details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A book comprising a plurality of sections having notches extending across their binding edges; reinforcing cords in said notches; and a continuous thread sewed through and extending obliquely upon the binding edges of said sections securing them together and such thread being resewed at each of its intersections with said reinforcing cords, substantially as described.

2. A book comprising a plurality of sections having notches extending across their binding edges and perforations in said sections near their binding edges in such positions that the perforations of one section will register with its next adjacent section; reinforcing cords in said notches and a continuous thread sewed through said perforations, sewing through three sections at each sewing, laced across the binding edges of said sections and resewed at each of the intersections with said reinforcing cords, substantially as described.

3. A book comprising a plurality of sections having notches extending across their binding edges; and perforations in said sections near their binding edges in such positions that the perforations of one section will register with its next adjacent section; reinforcing cords in said notches and a continuous thread sewed in perforations of one of said sections, laced across the binding edge of said section and resewed at each of its intersections with said reinforcing cords throughout the length of the binding edge of such section, then sewed through perforations of the first section and second section, laced across the binding edges of such sections and again resewed at each of its int-ersections with the reinforcing cords throughout the length of such first and second sections, then sewed through perforations in the first, second and third sections, laced across the binding edges of said first, second and third sections and again resewed at each of its intersections with said reinforcing cords, then in a like manner sewed through the remaining sections, sewing through three sections at each sewing, lacing across the binding edges of such sections and resewing at each of its intersections with said reinforcing cords to complete the securing of said sections together, and then securing the next to the last and last sections in the same manner that the first and second sections are secured, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WALTER F. VALTERS.
